IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 197,488, dated November27, 1877; application filed May 25, 1877.

To all whom it may concern:

Be it known that I, J OHANN Gnone Ons- TERLE, of Franciscoville, in thecounty of J ackson and State of Michigan, have invented an Improvementin Washing-Machines, of which the following is a specification:

The nature of my invention relates to an improvement in washing-machinesof that class wherein the fabrics to be cleansed are subjected to theaction of a vibrating squeezer; and it consists in a cradle, corrugatedon the sides and bottom, slatted at the ends, and suspended withina box,with a slatted squeezer within the cradle, the two being vibrated inopposite directions by the mechanism more fully hereinafter specified.

Figure 1 is a perspective view. Fig. 2 is a longitudinal verticalsection at a: x.

In the drawing, A represents a rectangular box, within which a cradle,B, is suspended at one end by hangers a a. This cradle is corrugated onthe bottom and sides, and slatted at both ends, as shown.

C is a squeezer, composed of two series or sets of slats set in aV-shaped frame, whose lower edge travels on cleats I), laid on the sidesof the bottom of the cradle. v

The top of the frame of the squeezer has two arms, 0, extending over thefree end of the eradle, where a transverse pin, (1, pivots them to thetop of a lever, D, pivoted between brackets at the end of the box. Thebottom of the cradle has two projecting sills, which are, by atransverse pin, a, suspended from and pivoted to the lower end of saidlever D.

The upper end of the lever-D is vibrated by a connecting-rod, E,strapped onto a cranked shaft, F, journaled across one end of the box,the said rod E playing through a slot in the end of the box, whichpermits the latter to be covered, to prevent the escape of steam andodors.

The squeezer-frame has a diaphragm, f, inserted between the two sets ofslats to prevent the rush of water through the same.

The fabrics are placed in the cradle on both sides of the sqeeezer, andas the cradle and squeezer are vibrated in opposite directions, thefabrics are alternately rolled and rubbed against the corrugatedsurfaces and squeezed between the slatted surfaces, while a current ofwater at each vibration is forced through the mass, to carry out thesoil removed by the rubbing and squeezing process.

What I claim as my invention is- In a washing-machine, the combinationof the cradle B, suspended and reoiprocated within a water-tight tank,and having solid and corrugated sides and bottom and open slatted ends,with the V-shaped slatted squeezer, reciprocated within and in theopposite direction from the motion of the said cradle, substantially asand for the purposes set forth J OHANN GEORG OESTERLE.
